Application filed September 11,1922.` Serial No. 587,481).

Thslnvention vrelates to boilers for generating steam, and is particularly directed to means for extracting a great amountof heat from the products bf combustion before the same are finally expelled.

Another object of the invention isto provide an improved water circulatingsystem.

lVith these` and other objects f in Lview which will be more apparent as the` specification proceeds, the invention resides in certain novel features `of constructiomand combination and arrangementpof parts, the essential elements of which. are hereinafter fully described, are particularly point-ed out in the appended claim, and are illustrated in the accompanying drawing, in which:

Fig. 1 is a front elevation of my improved boiler, part-s being brokenl away for the sake of clearness. i V

Fig. 2 is a vertical, .longitudinal sectional view of the same.

Like characters of reference refer to like parts in both views. i

The views show the boiler in somewhat skeleton form, it being understood that the the same to the supply pipes which areshown at 13.` The steamand water drums l() and 11 are preferably cylindrical in form and arranged at opposite sides of the deviceA and at the upper portion thereof as clearly shown in Fig. 1. A drum or boiler section ltwhich I shall hereinafter refer to as the water front is arranged at the front of the device and may be supported in any suitable framework or masonry indicated generally at 15. The water `front is connected by a pair of pipes 16 with the steam and water drums and 11. as shown in Fig. 1 and as indicated in dotted lines in Fig. 2.

Similarly there is arranged at the rear of the structure and between the steam and water drums 10 and 11 a water back 17 which is connected by pipes 18 with the steam and water `drums 10 and 11 atthe rear. Supported in any suitable mannerbetween the water front 14 and the water back 17 are aplurality of boiler sections 19, 20,

21, 22 and 23. It isor` course understood that there may be a greater or less number of` these boiler sections, but for the purpose of this description live will bc sufficient to indicate `the general scheme.` The live boiler elements 11)23` are flat tanks extending complet-ely across the space between the sidewalls `so that none of the aroducts of combustion can pass around t eendsof these members directly to the smoke exit. The boiler elements or sections `are relatively wide and are inclined forwardly and upwardly `toward thewater front, and are ar-` ranged at progressively decreased distances, as the boiler elements or sections approach the rear of the boiler, and are also disposed lin staggered relation one to the other to provide a continuous diagonal passage for the heating element. The lower portions of members 19, 21 and 23cxtend completely down to the door or masonry so that no heat or smoke canppass under them while the members and 22 extend completely to the roof of the masonry. In the operation, the smoke and heat strike against the {ire-brick placed at the base of member 19 and is then conducted in a course indicated by the arrows in Fig. 2. The various elements -19-23 are arranged in a manner that the cross-sectional area of the 'passage through which the products of combustion pass is suchthat there is an even, smooth and im interrupted flow of the products of combustion.` It is to be noted that in this manner the hot air and gases pass over both of the major surfaces of every one of the elements 19 to 23.

As the boiler elements 20 and 22pass out between steam and water drums 10 and 11 they are connected directly to the said steam and water drums 10 and 11 by pipes 26 and themembers 19, 21 and'23 are connected by depending pipes 27 The filial member 23 is connected by pipes 28 with the lower end of `the water back 17 and the lower portion of member 23 is connected by the pipes 29 to the rear ends of longitlildinally arranged ipes "30 extending from front to rear o the device and connectedat the front by risers 31 `withthe water front 111. The lower 'ends of the several members 19 to 22 are connected by respective pipes 32, 33, 34 and 35 with the respective pipes 30.

It will thus be seen that a complete ther- Ino-siphon circulation of the water is capable from any one of the elements' to any other, and if one of the elements absorbs heat faster than another, thereby `generating steam, this steam will be immediately passed into the steam aand'waterdrums 10 and l1 and the colder water from the other elements will be immediately circulated to this` `to anything less than the whole of my invention asset forth in the appended claim.

I claim: I In :i boiler structure including a lire-box therefor, the combination of a pair of horizontal interconnected drums parallel with the sides of the said strucure outwardly of and `adjacent the top, edge thereof, of front and rear substantially inverted L-shaped water backs, a plurallty of boiler sections y25 reliqtiye Wideag iglining forwardly and upward y toward "e said water front, said boiler sections being at progressively decreasing distance asthe sections a preach the rear of `the boiler,-said sections isposed in staggered relation one to the other to provide u continuous diagonal passage for the heating element, the foremost portion of each of said sections being o eratively connected to said drums and te back boiler section being operatively connected adjacent the bottom end thereof to the side of the said waterback, adjacent the bottom end therefor for e'ecting a thermo-siA hon circulation in saidboiler structure, the ottom portions of said boiler secti'ons'bein interconnected.

In testimony whereof I a x my signature.
